Computed tomography failures

Can CT scans make mistakes?
A CT scan can be wrong: it can't tell the difference between cancerous tissue and non-cancerous tissue.
CT scans can be misread or misinterpreted.
Imaging tests usually can't tell if a change has been caused by cancer.
CT scans can produce false negatives and false positives..
What are common faults in CT scan?
It often shows beam hardening artifacts.
If the sample is too lightly absorbing for the X-ray energy used to scan it, the projection images will be all bright, and the CT image will be dark with little-to-no contrast.
Therefore, this problem is caused by a mismatch of the sample absorption rate and the X-ray energy..

7 Common Problems with X-ray CT & How To Avoid Them
Resolution is too low.Can't scan the whole sample.CT image is all too dark or too bright.There is no density contrast.Scans take too long.Files are too big.Analysis is too involved..
What are the problems with computed tomography?
Concerns about CT scans include the risks from exposure to ionizing radiation and possible reactions to the intravenous contrast agent, or dye, which may be used to improve visualization..
What is the primary problem during CT imaging?
There are few direct risks associated with CT scanning.
These range from contrast-induced allergic reactions, contrast-induced nephropathy, and long term risk of cancer development due to radiation exposure.
Additional considerations include the patient's pregnancy status and radiation effect on the developing fetus..
Are There Any Risks? CT scans use X-rays, which produce ionizing radiation.
Research shows that this kind of radiation may damage your DNA and lead to cancer.
But the risk is still very small -- your chances of developing a fatal cancer because of a CT scan are about 1 in 2,000.
Misdiagnosis is a common but serious medical mistake.
According to new research, misreading of CT scans – one variety of patient misdiagnosis - is a leading cause of medical errors that harm patients.
There are few direct risks associated with CT scanning.
These range from contrast-induced allergic reactions, contrast-induced nephropathy, and long term risk of cancer development due to radiation exposure.
Additional considerations include the patient's pregnancy status and radiation effect on the developing fetus.

Common human error factors are: lack of time or warm-up routine correction, resulting in uniformity of the image is not normal or good, resulting in CT for patient positioning errors are not allowed to sweep out the image; patients wear a metal image artifacts caused by produce; the same time lead to a variety of

CT causes for the failure can be divided into three types: First, due to environmental factors caused the failure is not normal. The second is caused by the improper operation of the fault. Third, the CT component of aging itself, a qualitative change. Parameter drift leading to mechanical wear or failure.

CT causes for the failure can be divided into three types: First, due to environmental factors caused the failure is not normal. The second is caused by the

In one patient, the failure of CT scan to detect ischemic lesions may be attributable to less sensitive neuroradiologic criteria in use at the time of the
